COMBINED ELECTRIC TIME-STAMP AND SIGNAL DEVICE.

SPECIFICATION forming part of Letters Patent No. 509,21 7, dated November 21,1893.

Application filed March '7, 1891. Serial No. 384,172. (No model.)

To all whom it may concern.-

Be it known that I, THOMAS F. GAYNOR, of Louisville, county of Jefferson, State of Kentucky, have invented certain new and useful Improvements in a Combined Electric Time- Stamp and Signal Device, of which the followingis a specification, taken in connection with the accompanying drawings, in which like letters represent like parts.

The invention relates more particularly to municipal signal systems in which it is desirable to stamp upon apaper tape of a regis ter mechanism adapted to record the signals transmitted from an outlying signal box mechanism the time of the reception of such signals.

This invention also relates to that class of automatic signal devices which are adapted to automatically attract the attention of a person who shall send in a signal from a signal box mechanism.

The object of my invention is to simplify the design and construction of such devices and my invention therefore consists in combining a stamping machine and an automatic multiple circuit breaking machine in such a manner as that a single electro-magnet placed in electric connection with a relay circuit changing device in a signal circuit will not only stamp the time upon the tape of the register mechanism but will also cause itself to be cut out of circuit during the remainder of the time during which a signal is being registered on the tape after it has made a single impression, and furthermore will cause the ,circuit breaking machine to start and automatically give the required attention signal upon the'signal mechanism of the outlying signal box after the signal sent in from the same has been completed.

The invention also consists of such a novel combination of register mechanism and circuit mechanism as is required to make the whole device operative and complete.

Figure 1. represents a front view of the machine. Fig. 2. represents a top view of Fig. 1. Fig. 3. represents a diagram of the con nections between the outlying box mechanism and the several parts of the combined time stamp and automatic signal mechanism together with the arrangement of the Whole mechanism with relation to the register mechanism.

This automatic signaling mechanism is sometimes designated as an answer back device because after a person has sent in a signal as for instance,a police officer making his report signal in going his rounds, the machine, if set to do this, will, after the report signal has come in, signal to him an answer back that he is desired to remain at the signal box until special instructions may be given him or correspondence held from the central office. This part of theinvention will therefore be referred to as theanswerback machine.

The machine as will be noted by reference to Figs. 1. and 2. consists of two sections the right hand one containing a series of type wheels upon the peripheries of which the characters representing the minute, hour, a. m. and p. m. day of the month, name of the month, and year are placed and the whole mechanism being moved by a suitable clock work mechanism in the manner of the well known time stamping machines and needing no further description, as no claim is made for the clock work or wheel mechanism shown and as any other suitable time stamp mechanism can be used as well as the one herein shown and described.

In the left hand section of the machine the answer-back mechanism is shown as consisting of a multiple circuit breaking wheel upon which the contact springs of the several (four) outlying box circuits converge, and which is driven by a train of wheel work and having a detent lever mechanism somewhat similar to the usual wheel work of signal boxes. Between the answer-back mechanism and the time stamp mechanism a bell crank lever A. is placed which is trunnioned by means of the shaft A. in two lugs A A in one of the vertical frame plates A. of the machine.

ver A. a presser B. is secured by means of the pin B. which is adapted to press the tape of the register against the character wheels of the time stamp mechanism and thereby make the required time imprint on the paper. An

Upon the upper end A of the1einked ribbon passes between the wheels and the presser which may be either under or over the paper according as it may be desirable to have the imprint on the upper or under surface of the tape. The screw AAin the lever A. adjusts the surface of the presser to come squarely against the type wheels. A spring A". which is secured to the hinged cover G. for the type wheel mechanism presses against the under side of the lever A. and thereby keeps the presser 13. clear of the type Wheels when the machine isin its normalcondition. The tension of the spring A. is regulated by the tension screw A in the lever A. Near the lower end A of the lever A. an armature D. is secured which is adapted to be energized by the magnet D. which is placed beneath the answer back mechanism and which is secured to the base A of the machine by means of the standard A.

The circuit wheel shaft E. upon which the insulated circuit wheels E. E E E'*. E. are mounted has an escapement lever E. secured thereto. A detent A projects from the lever A. in such a manner as to arrest the rotation of the escapement lever E". and consequently the circuit wheel shaft mechanism when the magnets are demagnetized, as shown in the figures. The circuit wheel shaft E. is provided with a train of wheel work having a clock spring motor mechanism which is wound up by means of a key through the shaft F. the end F. of which is squared and projects through the end plate A of the machine. By this arrangement the detent A as has already been stated arrests the rotation of the circuit wheel shaft E. when the armature is in its normal or open circuit condition, but when the armature is drawn forward to the poles of the magnets in response to an electric current sent through the latter the detent A passes to the left of and clear of the escapement lever E. Which allows the circuit wheel shaft E. to rotate which it will continue to do until again arrested in its rotation by the dropping back again of the armature mechanism into its normal or open circuit position. This forward movement of the armature also causes the lever A. to bring the presser B. down upon the tape and against the type wheels and thereby cause an impression to be made upon the paper. The circuit wheels are insulated from the shaft and from each other and each circuit wheel has a set of insulated contact springs G. G. G provided for it which form circuit terminals for an outlying signal box circuit. The periphery of each of the circuit wheels is divided into three sections E E E". upon each one of which, a contact spring makes contact. The section E". which is a trifle smaller in diameter than the other parts of the circuit wheel is perfectly smooth and a spring G. makes a constant contact at all times during the rotation of the wheel but the sections E and E". have notches in their peripheries corresponding to the signal that is desired to be transmitted similar to the usual form of closed circuit wheels. See Fig.3. Circuit connection is established with the outlying circuits by means of the wires H. II. H and the insulated binding screws 11 ll. H in the base A of the machine. The circuit wheel E however, has only two sections and is provided with but two contact springs G 1. having wire connections with the insulated binding screws H. H in the base A of the machine. The section E of the circuitwheel is smooth like the small sections of the other wheels but its other section is provided with a single tooth E. see Fig. 3. upon which the terminal G. normally rests.

The purpose and operation of the machine will now be described, and can be more readily understood by referring to Fig. in which the essential parts are shown theoretically and by diagram only.

I. representsa circuit wheel of a signal box mechanism in an outlying box circuit having also an electric hell I which is sounded by the movements of an armature I which are effected by electric impulses sent through the magnet 1 over the circuit I the current being from the battery 1". at the central station. The magnet J. is placed in the circuit 1. having a trunnioned armature J. which is provided with a register pen J1, an insulated circuit closer J and a bell hammer J. The pen J is adapted to record signals upon the register tape K. of a register of the usual construction which regulates the movement of the tape during the reception of a signal and the type wheels L. of the time stampdevice are placed in close proximity to the register so that the tape after having the signal recorded upon it by the register will pass between the presser B. and the type wheels L. of the time stamping device. The circuit closer J closes a normally open circuit M. through the magnet D. which causes the armature D. to move against the poles of the magnet and not only bring the presser B. down upon the tape K. and thereby cause the time to be stamped upon the latter, but also draws the deteut A away from the end of the escapement lever E. and allows the circuit wheels upon the shaft E. to rotate from right to left as indicated by the arrow. The position of the mechanism shown in the diagram represents the local circuit M. as

just having been closed by the reception of the initial break in the circuit 1". caused by the starting of the circuit wheel I. which in turn caused the armature J. to drop away from the magnet J. and thereby closed the open circuit M. by means of the circuit closer J The local circuit M. is from the battery M. through the circuit closer J 1, the magnet D'., the wheel 12 its tooth E and the contact spring G. back to the battery. Now, it will be noticed that although the circuit wheel. shaft E. has barely commenced its rotation yet the contact spring G. is about to leave contact with thetooth E so that bythetirne the second notch of the signal wheel I. reaches the contact spring 1 and thereby causes the magnet J. to allow its armature J. to make the circuit closer J again close thelocal circuit M. the tooth E. of the circuit wheel E will have left contact with the spring G and therefore the circuit M. will be opened notwithstanding the 010s ure by the circuit closer J and no more impressions of the presser B.will be made upon the tape K. The time in which the circuit wheel I. makes its revolution is less than the time required for the shaft E. and consequently the circuit wheel E to make its revolution so that the circuit wheel I. will always have completed its signal before the tooth E of the circuit wheel E again makes contact with the contact spring G By this arrangement only a single impression of the time stamp mechanism will be made for each signal sent in from a signal box, this being the object and purpose of the single closure of the local circuit M. by the circuit wheel E and contact spring G The answer-back feature will now be explained.

It will be noticed that the main circuit 1 is through the wheel E through the contact spring G.and the switch N. Now, it will be supposed that it is desired to attract the attention of 'a patrolman when he makes his report call while operating the circuit wheel I. of the outlying signal box. The operator at the central station places the switch N. in the position shown in the diagram, at any time before the patrolman sends in his signal. Now, when the initial impulse of the signal from the wheel I. comes in it causes the local circuit M. to effect the release of the escapement lever E of the circuit wheel shaft E. as has already been described in referring to the operation of the time stamp mechanism. The circuit wheel E therefore rotates slowly keeping the circuitl closed at that point until the notch E reaches the spring G. which will cause a break to occur in the circuit and thereby make a signal upon the bell I. in the signal box and thereby give the desired attention or answer-back signal to the patrolman. On account of the slower time of the rotation of the shaft E. than that of the circuit wheel I. the latter will have completed its signal, as has already been explained with reference to the operation of the circuit closing wheel E so that the signal upon the bell 1. caused by the notch E in the circuit wheel E will come after the signals caused by the rotation of the circuit wheel I. which will have come to rest.

The operation of the circuit wheel E is precisely the same as that already described regarding the wheel E and in fact the wheels E and E both represent the two notched sections of the wheel E. in Fig. 1. they being only separated in the diagram for the purposes of clearness and better illustration. The wheel E is represented as having two notches which will give two signals upon the bell I. while the wheel E is shown with three notches which gives three signals upon the bell 1. Any other signals different to these can be obtained by making suitable notches in the wheels (or sections) E and E The wheel E is brought into circuit by throwing the switch N. upon the terminal N. and when it is desired to dispense with the answerback service this can be done by cutting out the answer-back wheels E E which is done by bringing the switch N. upon the terminal N The key 0. is for the purpose of signaling manually upon the hell I. and any independent signals that maybe desired to be given to the person at the outlying signal box. A switch P. having a short wire connection P. with the battery 1 is for the purpose of closing the circuit 1 through the magnet J. when brought upon the terminal P in case a break should occur in the line anywhere outside the central station. The object of this short circuiting of the circuit 1 is to prevent the armature J. from falling away from the magnet J. in case a break should occur in the line 1 outside of the central office and thereby cause the register and the time stamp and answ cr-back mechanism to operate unnecessarily. The relay mechanism which operates the circuit closer J is shown as being the armature pen mechanism of a register but any ordinary relay placed in the circuit 1 will operate the magnet D. as well as the one shown, but this, however, would necessitate the use of another office magnet in the circult I which is to be avoided if possible. This whole arrangement of having but one office magnet J. in the main circuit 1 to operate the register, the signal bell J and the time stamp mechanism and answer back device through the circuit ICC closer J and but one local circuit M. having only one magnet D. to operate both the time stamp and answer-back mechanism I believe to be new and reduces the amount of magnets and circuits requisite to a minimum.

The register mechanism which is represented by the wheels K. K may be of any of the usual forms of multiple pen registers having one magnet J. for each outlying box circuit in a municipal signal system, but as it is intended to Work in conjunction with the time stamping mechanism in recording the signal given from the signal box and in moving the tape between the presser and the type wheels of the time stamping device, it therefore becomes an element of the working combination. So also, the circuit connections and the mechanism contained therein as shown in Fig. 3. are required to make a practical working combination of the parts of the device.

K represents the escapement mechanism of the register mechanism which moves the tape K. and J represents the detent which controls its movement and which is shown as secured to the armature J.

The connections 1 1 1 having termi- :nals N. N N and the switch N. by which the wheels E E E". are brought into the circuit I as well as the short circuit connection I? with the circuit 1. having the switch P. and the terminal P in the circuit I by which the movement of the armature D. may be controlled in case of a break in the circuit 1 are also essential elements of the combination of the parts of the device.
